I am a huge proponent of negative learning, that you can learn more by taking on the opposite approach. Philosopher Nassim Taleb calls this “via negativa”. It is the idea that the best way to gain “happiness” in life isn’t chasing what makes us happy, but by vehemently avoiding what makes us unhappy (a long commute to work, a horrible micro-managing boss, poisonous and negative “friends”, and an expensive house mortgage).
I also believe strongly that one should never listen to “rules” of anything in life (especially street photography). However, below is a list of things (which has personally helped me) I avoid in street photography . Pick and choose what resonates with you, and leave the rest: http://digital-photography-school.com/50-things-i-try-to-avoid-in-street-photography
